Reversible Data Hiding Using an Improved Pixel Value Ordering and Complementary Strategy

open access: yesSymmetry, 2022
Reversible data hiding (RDH) schemes based on pixel value ordering have gained significant popularity due to their unique capability of providing high-quality marked images with a decent embedding capacity, while also enabling secret information extraction and the lossless recovery of the original images at the receiving side. However, the marked image

Dynamic Hybrid Reversible Data Hiding Based on Pixel-value-ordering

open access: yes電腦學刊, 2023
<p>Reversible data hiding (RDH) using pixel-value-ordering (PVO) is a well-established technique for embedding data in a cover image by modifying the maximum and minimum in each block. This paper proposes a dynamic hybrid RDH method based on PVO.

A Hybrid Reversible Data Hiding for Multiple Images With High Embedding Capacity

open access: yesIEEE Access, 2020
This paper proposed a high capacity reversible data hiding (RDH) scheme using three steganographic images, on which three successive embedding phases are performed.

Novel Reversible Pixel-Value-Ordering Technique for Secret Concealment

open access: yesIndian Journal of Science and Technology, 2015
This work is to preserve the distortion of marked image from the original image, that is, to improve the Peak Signal-to-Noise Ratio (PSNR) and to improve the Embedding Capacity (EC). Pixel-Value-Ordering (PVO) is the technique used for ensuring reversibility in Reversible Data Hiding (RDH).

AN EFFECTIVE REVERSIBLE DATA HIDING METHOD BASED ON PIXEL-VALUE-ORDERING

open access: yesJournal of Computer Science and Cybernetics, 2020
This paper presents a new effective reversible data hiding method based on pixel-value-ordering (iGePVO-K) which is improvement of a recent GePVO-K method that recently is considered as a PVO-used method having highest embedding capacity. In comparison with GePVO-K method, iGePVO-K has the following advantages.

Noise Removal of Low-Dose CT Images Using Modified Smooth Patch Ordering

open access: yesIEEE Access, 2017
Low-dose computed tomography (LDCT) images tend to be severely degraded by excessive mottle noise and steak artifacts. In this paper, an algorithm of modified smooth patch ordering (MSPO) is proposed to improve the LDCT images.

AN EFFICIENT REVERSIBLE DATA HIDING BASED ON IMPROVED PIXEL VALUE ORDERING METHOD

open access: yesJournal of Computer Science and Cybernetics, 2022
Pixel value ordering (PVO) has been considered as an effective reversible data hiding method for high embedding capacity and good imperceptibility. In this paper, we propose a novel reversible data hiding based on four sorted pixels.  This paper proposes a new reversible hiding scheme based on the arrangement of 4 pixels.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Spatial biology in cancer epigenetics

open access: yesMolecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
